-     * @param[in] input1          An input tensor info. Data types supported: U8/QS8/QS16/S16/F16/F32
-     * @param[in] input2          An input tensor info. Data types supported: U8, QS8 (only if @p input1 is QS8), QS16 (only if @p input1 is QS16), S16/F16 (only if @p input1 is F16), F32 (only if @p input1 is F32).
-     * @param[in] output          The output tensor info. Data types supported: U8 (Only if both inputs are U8), QS8 (only if both inputs are QS8), QS16 (only if both inputs are QS16), S16/F16 (only if @p input1 is F16), F32 (only if both inputs are F32).
+     * @note For @p scale equal to 1/255 only round to nearest even (implemented as round half up) is supported.
+     *       For all other scale values only round to zero (implemented as round towards minus infinity) is supported.
+     *       For QS8/QS16 scale = 1 is the only supported value.
